BazaarLive: Live Video Auctions for India's $16B Collectibles Market – Built for H0 Hackathon

Sakshi kesarwani — Sun, 28 Jun 2026 13:18:00 +0000

India Has ZERO Live Auction Platforms. I Built One.

Imagine selling a ₹50,000 Banarasi silk saree to a buyer in another city. You show it on WhatsApp photos (no trust). They ask for details (no video). You negotiate for hours (no real-time).

Indian collectibles market = $16 billion. Individual sellers = 45 million. Unserved users = 100 million. First-mover = 0 competitors.

This is the opportunity. I built BazaarLive – the Indian Whatnot – for H0: Hack the Zero Stack.

What I Built

BazaarLive is live video auctions for India's collectibles market. Sellers go live via camera, showcase silk sarees, antiques, or jewelry in real-time. Buyers watch, bid instantly, and win via secure Razorpay payments.

I use enterprise video streaming (LiveKit), real-time WebSocket bidding (sub-500ms) with OCC conflict resolution, 2 AI features (AI item descriptions and AI auction summaries), and AWS infrastructure (S3, DynamoDB, DSQL, IAM). 10% platform fee on every transaction. First-mover India. Production-ready with real payments and order tracking.

Trying to Improve Based on Feedback

⚠️ Live stream needs iOS optimization (currently best on desktop).
